程序如下。问数组mtable中的值是多少? #include
#define uchar unsigned char #define uint unsigned int //延时 void DelayMS(uint x) { uchar i; while(x--) { for(i=0;i<120;i++); } } //主程序 void main() { //数组的值需要确定 unsigned char mtable[]={}; uchar k; while(1) { for(k=0;k<4;k++){ P0=mtable[k]; DelayMS(500); } } }
A.
unsigned char mtable[]={0xff,0x55,0x0,0xff};
B.
unsigned char mtable[]={102,136,0,256};
C.
unsigned char mtable[]={0xAA,0x55,0x0,0xff};
D.
unsigned char mtable[]={0x66,0x99,0x0,0xff};
